With the way the division is today a guy like Calvin Brock has a good chance because he's not JUST a power puncher and he's not JUST a defensive fighter...Sam Peter right now is JUST a puncher and what makes champions good is if they are able to win how they would least like to for example Sam Peter at best wants 1st round KO's and at worst he wants to be able to fight hard for 12 rounds ( and especially hard in the championship rounds ) to come from behind to win.....Brock has shown he has the heart to get up and keep fighting and be successful at it

I never have been impressed with Tua either...great power but not active enough in the ring
